Chapter 1
Operation of Web-based Management
Initial
Configuration
This chapter instructs you how to configure and manage the
ET42202M-S-PD
through the web user interface. With this facility, you
can easily access and monitor through any one port of the switch all the
status of the switch, including MIBs status, each port activity, Spanning tree
status, port aggregation status, multicast traffic, VLAN and priority status,
even illegal access record and so on.
T
he default values of the ET42202M-S-PD are listed in the table below:
IP Address
192.168.2.1
Subnet Mask
255.255.255.0
Default
192.168.2.254
Username
admin
Password
system
After the ET42202M-S-PD has been finished configuration the it interface,
you can browse it. For instance, type http://192.168.2.1 in the address
row in a browser, it will show the following screen and ask you inputting
username and password in order to login and access authentication.
The default username is “admin” and password is system. For the first
time to use, please enter the default username and password, and then click
the <Login> button. The login process now is completed. In this login menu,
you have to input the complete username and password respectively, the
ET42202M-S-PD will not give you a shortcut to username automatically.
This looks inconvenient,
but safer.
In the ET42202M-S-PD, allowed two or more users using administrator’s
identity to manage this switch, which administrator to do the last setting, it
will be an available configuration to effect the system.

NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean
Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an
user-defined NTP server as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update
the time periodically without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then perform
time sync via NTP because the switch will combine this time zone offset and updated NTP time
to come out the local time, otherwise, you will not able to get the correct time. The switch
supports configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.

2-2 Green Ethernet
EEE is a power saving option that reduces the power usage when there is low or no traffic
utilization.
EEE works by powering down circuits when there is no traffic. When a port gets data to be
transmitted all circuits are powered up. The time it takes to power up the circuits is named
wakeup time. The default wakeup time is 17 us for 1Gbit links and 30 us for other link speeds.
EEE devices must agree upon the value of the wakeup time in order to make sure that both the
receiving and transmitting device has all circuits powered up when traffic is transmitted. The
devices can exchange wakeup time information using the LLDP protocol.
EEE works for ports in auto-negotiation mode, where the port is negotiated to either 1G or 100
Mbit full duplex mode.
For ports that are not EEE-capable the corresponding EEE checkboxes are grayed out and

www.ot-systems.com Ver.1.0
15
thus impossible to enable EEE for.
When a port is powered down for saving power, outgoing traffic is stored in a buffer until the
port is powered up again. Because there are some overhead in turning the port down and up,
more power can be saved if the traffic can be buffered up until a large burst of traffic can be
transmitted. Buffering traffic will give some latency in the traffic.
Web Interface
To configure a Port Power Saving Configuration in the web interface:
1. Click Configuration, Green Ethernet
2. Evoke to enable or disable the ActiPHY, PerfectReach, EEE and EEE Urgent Queues .

PerfectReach :
Cable length power savings enabled.
PerfectReach works by determining the cable length and lowering the power for
ports with short cables.
EEE :
Controls whether EEE is enabled for this switch port.
For maximizing power savings, the circuit isn't started at once transmit data is
ready for a port, but is instead queued until a burst of data is ready to be
transmitted. This will give some traffic latency.
If desired it is possible to minimize the latency for specific frames, by mapping the
frames to a specific queue (done with QOS), and then mark the queue as an
urgent queue. When an urgent queue gets data to be transmitted, the circuits will
be powered up at once and the latency will be reduced to the wakeup time.

When Auto Speed is selected on a port, this section indicates the flow control
capability that is advertised to the link partner. When a fixed-speed setting is
selected, that is what is used. The Current Rx column indicates whether pause
frames on the port are obeyed, and the Current Tx column indicates whether
pause frames on the port are transmitted. The Rx and Tx settings are determined
by the result of the last Auto-Negotiation.
Check the configured column to use flow control. This setting is related to the
setting for Configured Link Speed.

2-4.3 Relay
A DHCP relay agent is used to forward and to transfer DHCP messages between the clients
and the server when they are not in the same subnet domain. It stores the incoming interface
IP address in the GIADDR field of the DHCP packet. The DHCP server can use the value of
GIADDR field to determine the assigned subnet. For such condition, please make sure the
switch configuration of VLAN interface IP address and PVID(Port VLAN ID) correctly.

2-5.1.7 SNMP
Any Network Management System (NMS) running the Simple Network Management Protocol
(SNMP) can manage the Managed devices equipped with SNMP agent, provided that the
Management Information Base (MIB) is installed correctly on the managed devices. The
SNMP is a protocol that is used to govern the transfer of information between SNMP manager
and agent and traverses the Object Identity (OID) of the management Information Base (MIB),
described in the form of SMI syntax. SNMP agent is running on the switch to response the
request issued by SNMP manager.
Basically, it is passive except issuing the trap information. The switch supports a switch to turn
on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP agent will be started up.
All supported MIB OIDs, including RMON MIB, can be accessed via SNMP manager. If the
field SNMP is set “Disable”, SNMP agent will be de-activated, the related Community Name,
Trap Host IP Address, Trap and all MIB counters will be ignored.
2-5.1.7.1 System
This section describes how to configure SNMP System on the switch. This function is used to
configure SNMP settings, community name, trap host and public traps as well as the throttle
of SNMP. A SNMP manager must pass the authentication by identifying both community
names, then it can access the MIB information of the target device. So, both parties must
have the same community name. Once completing the setting, click <Apply> button, the
setting takes effect.

Engine ID
An octet string identifying the engine ID that this entry should belong to. The
string must contain an even number (in hexadecimal format) with number of
digits between 10 and 64, but all-zeros and all-'F's are not allowed. The SNMPv3
architecture uses the User-based Security Model (USM) for message security and
the View-based Access Control Model (VACM) for access control. For the USM
entry, the usmUserEngineID and usmUserName are the entry's keys. In a simple
agent, usmUserEngineID is always that agent's own snmpEngineID value. The
value can also take the value of the snmpEngineID of a remote SNMP engine with
which this user can communicate. In other words, if user engine ID equal system
engine ID then it is local user; otherwise it's remote user.

Parameter description:
System Configuration
Mode :
Indicates if Limit Control is globally enabled or disabled on the switch. If globally disabled,
other modules may still use the underlying functionality, but limit checks and corresponding
actions are disabled.
Aging Enabled :
If checked, secured MAC addresses are subject to aging as discussed under Aging Period .
Aging Period :
If Aging Enabled is checked, then the aging period is controlled with this input. If other
modules are using the underlying port security for securing MAC addresses, they may have
other requirements to the aging period. The underlying port security will use the shorter
requested aging period of all modules that use the functionality.
The Aging Period can be set to a number between 10 and 10,000,000 seconds.
To understand why aging may be desired, consider the following scenario: Suppose an
end-host is connected to a 3rd party switch or hub, which in turn is connected to a port on
this switch on which Limit Control is enabled. The end-host will be allowed to forward if the
limit is not exceeded. Now suppose that the end-host logs off or powers down. If it wasn't for
aging, the end-host would still take up resources on this switch and will be allowed to
forward. To overcome this situation, enable aging. With aging enabled, a timer is started
once the end-host gets secured. When the timer expires, the switch starts looking for
frames from the end-host, and if such frames are not seen within the next Aging Period, the
end-host is assumed to be disconnected, and the corresponding resources are freed on the
switch.
Port Configuration
The table has one row for each port on the selected switch and a number of columns, which
are:
Port :
The port number to which the configuration below applies.
Mode :
Controls whether Limit Control is enabled on this port. Both this and the Global Mode must
be set to Enabled for Limit Control to be in effect. Notice that other modules may still use the
underlying port security features without enabling Limit Control on a given port.
Limit :
The maximum number of MAC addresses that can be secured on this port. This number
cannot exceed 1024. If the limit is exceeded, the corresponding action is taken.
The switch is "born" with a total number of MAC addresses from which all ports draw
whenever a new MAC address is seen on a Port Security-enabled port. Since all ports draw
from the same pool, it may happen that a configured maximum cannot be granted, if the
remaining ports have already used all available MAC addresses.
Action :
If Limit is reached, the switch can take one of the following actions:
None: Do not allow more than Limit MAC addresses on the port, but take no further action.
Trap: If Limit + 1 MAC addresses is seen on the port, send an SNMP trap. If Aging is
disabled, only one SNMP trap will be sent, but with Aging enabled, new SNMP traps will be
sent every time the limit gets exceeded.
Shutdown: If Limit + 1 MAC addresses is seen on the port, shut down the port. This implies
that all secured MAC addresses will be removed from the port, and no new address will be
learned. Even if the link is physically disconnected and reconnected on the port (by
disconnecting the cable), the port will remain shut down. There are three ways to re-open

Parameter description:
Mode :
Indicates if NAS is globally enabled or disabled on the switch. If globally disabled, all ports
are allowed forwarding of frames.
Reauthentication Enabled :
If checked, successfully authenticated supplicants/clients are reauthenticated after the
interval specified by the Reauthentication Period. Reauthentication for 802.1X-enabled
ports can be used to detect if a new device is plugged into a switch port or if a supplicant is
no longer attached.
For MAC-based ports, reauthentication is only useful if the RADIUS server configuration
has changed. It does not involve communication between the switch and the client, and
therefore doesn't imply that a client is still present on a port (see Aging Period below).
Reauthentication Period :
Determines the period, in seconds, after which a connected client must be reauthenticated.
This is only active if the Reauthentication Enabled checkbox is checked. Valid values are in
the range 1 to 3600 seconds.
EAPOL Timeout :
Determines the time for retransmission of Request Identity EAPOL frames.
Valid values are in the range 1 to 255 seconds. This has no effect for MAC-based ports.
Aging Period :
This setting applies to the following modes, i.e. modes using the Port Security functionality
to secure MAC addresses:
• Single 802.1X
• Multi 802.1X
• MAC-Based Auth.
When the NAS module uses the Port Security module to secure MAC addresses, the Port
Security module needs to check for activity on the MAC address in question at regular
intervals and free resources if no activity is seen within a given period of time. This
parameter controls exactly this period and can be set to a number between 10 and 1000000
seconds.
If reauthentication is enabled and the port is in an 802.1X-based mode, this is not so critical,
since supplicants that are no longer attached to the port will get removed upon the next
reauthentication, which will fail. But if reauthentication is not enabled, the only way to free
resources is by aging the entries.
For ports in MAC-based Auth. mode, reauthentication doesn't cause direct communication
between the switch and the client, so this will not detect whether the client is still attached or
not, and the only way to free any resources is to age the entry.
Hold Time :
This setting applies to the following modes, i.e. modes using the Port Security functionality

to secure MAC addresses:
• Single 802.1X
• Multi 802.1X
• MAC-Based Auth.
If a client is denied access - either because the RADIUS server denies the client access or
because the RADIUS server request times out (according to the timeout specified on the
"Configuration→Security→AAA" page) - the client is put on hold in the Unauthorized state.
The hold timer does not count during an on-going authentication.
In MAC-based Auth. mode, the The switch will ignore new frames coming from the client
during the hold time.
The Hold Time can be set to a number between 10 and 1000000 seconds.
RADIUS-Assigned QoS Enabled :
RADIUS-assigned QoS provides a means to centrally control the traffic class to which traffic
coming from a successfully authenticated supplicant is assigned on the switch. The
RADIUS server must be configured to transmit special RADIUS attributes to take advantage
of this feature (see RADIUS-Assigned QoS Enabled below for a detailed description)
The "RADIUS-Assigned QoS Enabled" checkbox provides a quick way to globally
enable/disable RADIUS-server assigned QoS Class functionality. When checked, the
individual ports' ditto setting determine whether RADIUS-assigned QoS Class is enabled on
that port. When unchecked, RADIUS-server assigned QoS Class is disabled on all ports.
RADIUS-Assigned VLAN Enabled :
RADIUS-assigned VLAN provides a means to centrally control the VLAN on which a
successfully authenticated supplicant is placed on the switch. Incoming traffic will be
classified to and switched on the RADIUS-assigned VLAN. The RADIUS server must be
configured to transmit special RADIUS attributes to take advantage of this feature (see
RADIUS-Assigned VLAN Enabled below for a detailed description).
The "RADIUS-Assigned VLAN Enabled" checkbox provides a quick way to globally
enable/disable RADIUS-server assigned VLAN functionality. When checked, the individual
ports' ditto setting determine whether RADIUS-assigned VLAN is enabled on that port.
When unchecked, RADIUS-server assigned VLAN is disabled on all ports.
Guest VLAN Enabled :
A Guest VLAN is a special VLAN - typically with limited network access - on which
802.1X-unaware clients are placed after a network administrator-defined timeout. The
switch follows a set of rules for entering and leaving the Guest VLAN as listed below.
The "Guest VLAN Enabled" checkbox provides a quick way to globally enable/disable
Guest VLAN functionality. When checked, the individual ports' ditto setting determines
whether the port can be moved into Guest VLAN. When unchecked, the ability to move to
the Guest VLAN is disabled on all ports.
Guest VLAN ID :
This is the value that a port's Port VLAN ID is set to if a port is moved into the Guest VLAN.
It is only changeable if the Guest VLAN option is globally enabled.
Valid values are in the range [1; 4095].
Max. Reauth. Count :
The number of times the switch transmits an EAPOL Request Identity frame without
response before considering entering the Guest VLAN is adjusted with this setting. The
value can only be changed if the Guest VLAN option is globally enabled.
Valid values are in the range [1; 255].
Allow Guest VLAN if EAPOL Seen :
The switch remembers if an EAPOL frame has been received on the port for the life-time of
the port. Once the switch considers whether to enter the Guest VLAN, it will first check if this
option is enabled or disabled. If disabled (unchecked; default), the switch will only enter the
Guest VLAN if an EAPOL frame has not been received on the port for the life-time of the

port. If enabled (checked), the switch will consider entering the Guest VLAN even if an
EAPOL frame has been received on the port for the life-time of the port.
The value can only be changed if the Guest VLAN option is globally enabled.
Port Configuration :
The table has one row for each port on the selected switch and a number of columns, which
are:
Port :
The port number for which the configuration below applies.
Admin State :
If NAS is globally enabled, this selection controls the port's authentication mode. The
following modes are available:
Force Authorized :
In this mode, the switch will send one EAPOL Success frame when the port link comes up,
and any client on the port will be allowed network access without authentication.
Force Unauthorized :
In this mode, the switch will send one EAPOL Failure frame when the port link comes up,
and any client on the port will be disallowed network access.
Port-based 802.1X :
In the 802.1X-world, the user is called the supplicant, the switch is the authenticator, and the
RADIUS server is the authentication server. The authenticator acts as the
man-in-the-middle, forwarding requests and responses between the supplicant and the
authentication server. Frames sent between the supplicant and the switch are special
802.1X frames, known as EAPOL (EAP Over LANs) frames. EAPOL frames encapsulate
EAP PDUs (RFC3748). Frames sent between the switch and the RADIUS server are
RADIUS packets. RADIUS packets also encapsulate EAP PDUs together with other
attributes like the switch's IP address, name, and the supplicant's port number on the switch.
EAP is very flexible, in that it allows for different authentication methods, like
MD5-Challenge, PEAP, and TLS. The important thing is that the authenticator (the switch)
doesn't need to know which authentication method the supplicant and the authentication
server are using, or how many information exchange frames are needed for a particular
method. The switch simply encapsulates the EAP part of the frame into the relevant type
(EAPOL or RADIUS) and forwards it.
When authentication is complete, the RADIUS server sends a special packet containing a
success or failure indication. Besides forwarding this decision to the supplicant, the switch
uses it to open up or block traffic on the switch port connected to the supplicant
N
OTE
:
Suppose two backend servers are enabled and that
the server timeout is configured to X seconds (using the AAA
configuration page), and suppose that the first server in the
list is currently down (but not considered dead).
Now, if the supplicant retransmits EAPOL Start frames at a
rate faster than X seconds, then it will never get
authenticated, because the switch will cancel on-going
backend authentication server requests whenever it receives
a new EAPOL Start frame from the supplicant.
And since the server hasn't yet failed (because the X seconds
haven't expired), the same server will be contacted upon the
next backend authentication server request from the switch.
This scenario will loop forever. Therefore, the server timeout
should be smaller than the supplicant's EAPOL Start frame
retransmission rate.

Single 802.1X :
In port-based 802.1X authentication, once a supplicant is successfully authenticated on a
port, the whole port is opened for network traffic. This allows other clients connected to the
port (for instance through a hub) to piggy-back on the successfully authenticated client and
get network access even though they really aren't authenticated. To overcome this security
breach, use the Single 802.1X variant. Single 802.1X is really not an IEEE standard, but
features many of the same characteristics as does port-based 802.1X. In Single 802.1X, at
most one supplicant can get authenticated on the port at a time. Normal EAPOL frames are
used in the communication between the supplicant and the switch. If more than one
supplicant is connected to a port, the one that comes first when the port's link comes up will
be the first one considered. If that supplicant doesn't provide valid credentials within a
certain amount of time, another supplicant will get a chance. Once a supplicant is
successfully authenticated, only that supplicant will be allowed access. This is the most
secure of all the supported modes. In this mode, the Port Security module is used to secure
a supplicant's MAC address once successfully authenticated.
Multi 802.1X :
In port-based 802.1X authentication, once a supplicant is successfully authenticated on a
port, the whole port is opened for network traffic. This allows other clients connected to the
port (for instance through a hub) to piggy-back on the successfully authenticated client and
get network access even though they really aren't authenticated. To overcome this security
breach, use the Multi 802.1X variant.
Multi 802.1X is really not an IEEE standard, but features many of the same characteristics
as does port-based 802.1X. Multi 802.1X is - like Single 802.1X - not an IEEE standard, but
a variant that features many of the same characteristics. In Multi 802.1X, one or more
supplicants can get authenticated on the same port at the same time. Each supplicant is
authenticated individually and secured in the MAC table using the Port Security module.
In Multi 802.1X it is not possible to use the multicast BPDU MAC address as destination
MAC address for EAPOL frames sent from the switch towards the supplicant, since that
would cause all supplicants attached to the port to reply to requests sent from the switch.
Instead, the switch uses the supplicant's MAC address, which is obtained from the first
EAPOL Start or EAPOL Response Identity frame sent by the supplicant. An exception to
this is when no supplicants are attached. In this case, the switch sends EAPOL Request
Identity frames using the BPDU multicast MAC address as destination - to wake up any
supplicants that might be on the port.
The maximum number of supplicants that can be attached to a port can be limited using the
Port Security Limit Control functionality.
MAC-based Auth.:
Unlike port-based 802.1X, MAC-based authentication is not a standard, but merely a
best-practices method adopted by the industry. In MAC-based authentication, users are
called clients, and the switch acts as the supplicant on behalf of clients. The initial frame
(any kind of frame) sent by a client is snooped by the switch, which in turn uses the client's
MAC address as both username and password in the subsequent EAP exchange with the
RADIUS server. The 6-byte MAC address is converted to a string on the following form
"xx-xx-xx-xx-xx-xx", that is, a dash (-) is used as separator between the lower-cased
hexadecimal digits. The switch only supports the MD5-Challenge authentication method, so
the RADIUS server must be configured accordingly.
When authentication is complete, the RADIUS server sends a success or failure indication,
which in turn causes the switch to open up or block traffic for that particular client, using the
Port Security module. Only then will frames from the client be forwarded on the switch.
There are no EAPOL frames involved in this authentication, and therefore, MAC-based
Authentication has nothing to do with the 802.1X standard.
The advantage of MAC-based authentication over port-based 802.1X is that several clients
can be connected to the same port (e.g. through a 3rd party switch or a hub) and still require
individual authentication, and that the clients don't need special supplicant software to
authenticate. The advantage of MAC-based authentication over 802.1X-based
authentication is that the clients don't need special supplicant software to authenticate. The
disadvantage is that MAC addresses can be spoofed by malicious users - equipment whose
MAC address is a valid RADIUS user can be used by anyone. Also, only the
MD5-Challenge method is supported. The maximum number of clients that can be attached

to a port can be limited using the Port Security Limit Control functionality.
RADIUS-Assigned QoS Enabled :
When RADIUS-Assigned QoS is both globally enabled and enabled (checked) on a given
port, the switch reacts to QoS Class information carried in the RADIUS Access-Accept
packet transmitted by the RADIUS server when a supplicant is successfully authenticated. If
present and valid, traffic received on the supplicant's port will be classified to the given QoS
Class. If (re-)authentication fails or the RADIUS Access-Accept packet no longer carries a
QoS Class or it's invalid, or the supplicant is otherwise no longer present on the port, the
port's QoS Class is immediately reverted to the original QoS Class (which may be changed
by the administrator in the meanwhile without affecting the RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
• Single 802.1X
RADIUS attributes used in identifying a QoS Class:
Refer to the written documentation for a description of the RADIUS attributes needed in
order to successfully identify a QoS Class. The User-Priority-Table attribute defined in
RFC4675 forms the basis for identifying the QoS Class in an Access-Accept packet.
Only the first occurrence of the attribute in the packet will be considered, and to be valid, it
must follow this rule:
• All 8 octets in the attribute's value must be identical and consist of ASCII characters in the
range '0' - '3', which translates into the desired QoS Class in the range [0; 3].
RADIUS-Assigned VLAN Enabled :
When RADIUS-Assigned VLAN is both globally enabled and enabled (checked) for a given
port, the switch reacts to VLAN ID information carried in the RADIUS Access-Accept packet
transmitted by the RADIUS server when a supplicant is successfully authenticated. If
present and valid, the port's Port VLAN ID will be changed to this VLAN ID, the port will be
set to be a member of that VLAN ID, and the port will be forced into VLAN unaware mode.
Once assigned, all traffic arriving on the port will be classified and switched on the
RADIUS-assigned VLAN ID.
If (re-)authentication fails or the RADIUS Access-Accept packet no longer carries a VLAN
ID or it's invalid, or the supplicant is otherwise no longer present on the port, the port's
VLAN ID is immediately reverted to the original VLAN ID (which may be changed by the
administrator in the meanwhile without affecting the RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
• Single 802.1X
For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN Membership
and VLAN Port" pages. These pages show which modules have (temporarily) overridden
the current Port VLAN configuration.
RADIUS attributes used in identifying a VLAN ID:
RFC2868 and RFC3580 form the basis for the attributes used in identifying a VLAN ID in an
Access-Accept packet. The following criteria are used:
• The Tunnel-Medium-Type, Tunnel-Type, and Tunnel-Private-Group-ID attributes must all
be present at least once in the Access-Accept packet.
• The switch looks for the first set of these attributes that have the same Tag value and fulfil
the following requirements (if Tag == 0 is used, the Tunnel-Private-Group-ID does not need
to include a Tag):
- Value of Tunnel-Medium-Type must be set to "IEEE-802" (ordinal 6).
- Value of Tunnel-Type must be set to "VLAN" (ordinal 13).
- Value of Tunnel-Private-Group-ID must be a string of ASCII chars in the range '0' - '9',
which is interpreted as a decimal string representing the VLAN ID. Leading '0's are
discarded. The final value must be in the range [1; 4095].

Guest VLAN Enabled :
When Guest VLAN is both globally enabled and enabled (checked) for a given port, the
switch considers moving the port into the Guest VLAN according to the rules outlined below.
This option is only available for EAPOL-based modes, i.e.:
• Port-based 802.1X
• Single 802.1X
• Multi 802.1X
For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN Membership
and VLAN Port" pages. These pages show which modules have (temporarily) overridden
the current Port VLAN configuration.
Guest VLAN Operation:
When a Guest VLAN enabled port's link comes up, the switch starts transmitting EAPOL
Request Identity frames. If the number of transmissions of such frames exceeds Max.
Reauth. Count and no EAPOL frames have been received in the meanwhile, the switch
considers entering the Guest VLAN. The interval between transmission of EAPOL Request
Identity frames is configured with EAPOL Timeout. If Allow Guest VLAN if EAPOL Seen is
enabled, the port will now be placed in the Guest VLAN. If disabled, the switch will first
check its history to see if an EAPOL frame has previously been received on the port (this
history is cleared if the port link goes down or the port's Admin State is changed), and if not,
the port will be placed in the Guest VLAN. Otherwise it will not move to the Guest VLAN, but
continue transmitting EAPOL Request Identity frames at the rate given by EAPOL Timeout.
Once in the Guest VLAN, the port is considered authenticated, and all attached clients on
the port are allowed access on this VLAN. The switch will not transmit an EAPOL Success
frame when entering the Guest VLAN.
While in the Guest VLAN, the switch monitors the link for EAPOL frames, and if one such
frame is received, the switch immediately takes the port out of the Guest VLAN and starts
authenticating the supplicant according to the port mode. If an EAPOL frame is received,
the port will never be able to go back into the Guest VLAN if the "Allow Guest VLAN if
EAPOL Seen" is disabled.
Port State :
The current state of the port. It can undertake one of the following values:
Globally Disabled: NAS is globally disabled.

2-5.2.3 ACL
The GEPoEL2P-ESW26G Series switch access control list (ACL) is probably the most
commonly used object in the IOS. It is used for packet filtering but also for selecting types of
traffic to be analyzed, forwarded, or influenced in some way. The ACLs are divided into Ether
Types. IPv4, ARP protocol, MAC and VLAN parameters etc. Here we will just go over the
standard and extended access lists for TCP/IP. As you create ACEs for ingress classification,
you can assign a policy for each port, the policy number is 1-8, however, each policy can be
applied to any port. This makes it very easy to determine what type of ACL policy you will be
working with.

2-5.2.3.3 Access Control List
The section describes how to configure Access Control List rule. An Access Control List (ACL)
is a sequential list of permit or deny conditions that apply to IP addresses, MAC addresses, or
other more specific criteria. This switch tests ingress packets against the conditions in an ACL
one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as soon
as it matches a deny rule. If no rules match, the frame is accepted. Other actions can also be
invoked when a matching packet is found, including rate limiting, copying matching packets to
another port or to the system log, or shutting down a port.
This page shows the Access Control List (ACL), which is made up of the ACEs defined on this
switch. Each row describes the ACE that is defined. The maximum number of ACEs is 256 on
each switch. Click on the lowest plus sign to add a new ACE to the list. The reserved ACEs
used for internal protocol, cannot be edited or deleted, the order sequence cannot be changed
the priority is highest
Web Interface
To configure Access Control List in the web interface:
1. Click Configuration, ACL, then Configuration
2. Click the button to add a new ACL, or use the other ACL
modification buttons to specify the editing action (i.e., edit, delete, or
moving the relative position of entry in the list)
3. To specific the parameter of the ACE
4. Click the save to save the setting
5. If you want to cancel the setting then you need to click the reset button.
It will revert to previously saved values.
6. When editing an entry on the ACE Configuration page, note that the
Items displayed depend on various selections, such as Frame Type and IP Protocol Type.
Specify the relevant criteria to be matched for this rule,
and set the actions to take when a rule is matched (such as Rate Limiter,
Port Copy, Logging, and Shutdown).
